Mr. Boncassen arrives in England as a man of wealth and ideas, debating monarchy with the Duke himself and earning a respect the Duke would never extend to his daughter as a daughter-in-law. He is no social climber — his daughter's insistence that she will not force herself on a family that repudiates her reflects his own dignified independence. His presence forces the Pallisers to confront whether their objections to Isabel are about the girl or about the nation she comes from.
